It was first developed in 1959 and was based on a unidimensional model of impulsiveness which included it as a part of a larger groups of personality pre-dispositions such as extraversion, sensation seeking, and a lack of inhibitory behavioural controls.

Further research lead Barratt to classify impulsivity in three main aspects: motor (acting without thinking), cognitive (quick decisions), and non-planning (present orientation).
The second version, the BIS-11, was released in 1995.[1]

The BIS-11 is a 30-item self-report questionnaire, that is scored to yield a total score, three second-order factors, and six first-order factors. The questions are published in the 1995 references article. The following is a list of the items contributing to each factor score.[2]
